CESM1.2.z - Bug in config_grid for a couple of tri-grid setups

[aliceb]

Affected Releases - CESM1.2.z(Bugzilla 1882) If you try to set up an ne120_f09_g16 or ne120_f02_t12 case, the grids are not
set correctly because of a missing underscore in config_grid.xml. There is no
separator between the ocean grid [gx1v6 or tx0.1v2] and the r% header
indicating the name of the runoff. This results in the following output from
create_newcase:

ATM_GRID = ne120np4 NX_ATM=777602 NY_ATM=1
LND_GRID = 0.23x0.31 NX_LND=1152 NX_LND=768
ICE_GRID = 0.23x0.31 NX_ICE=1152 NX_ICE=768
OCN_GRID = 0.23x0.31 NX_OCN=1152 NX_OCN=768
ROF_GRID = r05 NX_ROF=720 NX_ROF=360
GLC_GRID = 0.23x0.31 NX_GLC=1152 NX_GLC=768
WAV_GRID = null NX_WAV=0 NX_WAV=0

rather than

ATM_GRID = ne120np4 NX_ATM=777602 NY_ATM=1
LND_GRID = 0.23x0.31 NX_LND=1152 NX_LND=768
ICE_GRID = tx0.1v2 NX_ICE=3600 NX_ICE=2400
OCN_GRID = tx0.1v2 NX_OCN=3600 NX_OCN=2400
ROF_GRID = r05 NX_ROF=720 NX_ROF=360
GLC_GRID = 0.23x0.31 NX_GLC=1152 NX_GLC=768
WAV_GRID = null NX_WAV=0 NX_WAV=0

In the first set, the land, ice, and ocean grids are all 0.23x0.31 rather than
the ice and ocean grids being tx0.1v2.
